Facts of the periodic table While Dmitri Mendeleev is most often cited as the inventor of the modern periodic table‚ his table was just the first to gain scientific credibility‚ and not the first table that organized the elements according to periodic properties. There are 90 elements on the periodic table that occur in nature. All of the other elements are strictly man-made. Technetium was the first element to be made artificially.

Greek philosophers are sometimes called NATURAL PHILOSOPHERS because they were mainly concerned with the natural world and it’s processes - Pythagoras (570 B.C)‚ Heraclitus (500 B.C)‚ Empedocles (490 B.C.)‚ Zeno (490 B.C.)‚ Parmenides (470 B.C.)‚ Democritus (460 B.C.) = Pre-Socratic - All the earliest philosophers shared the belief that there had to be a certain basic substance at the root of all change Pythagoras - Basic Beliefs: • He held the soul to be immortal • Transmigration of the soul

When he finished the training he stayed in Athens absorbing the philosophies of Plato‚ Aristotle‚ and Democritus. He eventually returned to his home in Samos where he started his own school‚ The Garden. The reason the school was called The Garden is because its location was‚ believe it or not‚ his own garden.

Ancient Greek philosophers – Democritus and Leucippus suggested that if we go on dividing matter‚ a stage will come when particles obtained cannot be divided further. Democritus called these indivisible particles atoms (meaning indivisible). How and why elements combine and what happens when they combine. Antoine L. Lavoisier laid the foundation of

theory that unified the four forces but could never achieve it‚ the difficulty was great in essence a theory of everything should explain that everything in the universe is made and why it is so. This question was already asked by philosophers like Democritus in the fourth century before our era‚ he thought that if you divide something in two and then one of its parts you cut it again and so as many times as possible should come a time when you would find an object that you could no longer divide‚ called
